Fluorescent bulbs typically do not work in cold outdoor temps. Does this bulb work in cold temps, 32 to zero or even below zero?

I honestly can't answer for sure about this particular bulb because we just got them this spring. However, we had fluorescent bulbs outside our garage all winter and they never stopped working, even when we hit -34, twice. So my expectation is that these will also work all winter, but I guess we'll just have to wait and see.

Sorry, I can't answer since I did not order my bulbs until sometime in mid April 2014. they have worked GREAT since then, but no really cold weather.

We had one of our coldest winters here in Missouri - sorry I do not remember how cold it got - but we didn't have any problems.

Just installed these, but have used other fluorescent blubs without the electric eye and they have worked for the past 3-4 years in Wisconsin with our temps.

I've used one outside, starting in Feb of the latest Boston winter, and it is still working great.

I purchased these at the end of April and I am not sure what the weather was at night back then. I can tell you though that we have these type of bulbs in outside fixtures on the building and in the courtyard (however they are not dawn to dusk) and they worked just fine this past horrible Chicago winter!

the Bulb is not weather resistant however I don't believe the cold will affect it is very dim though

They are not bad. I have had some 13 watts bulbs come on faster.. but it is not like it takes a minute before you see bright light. I do not know on cold weather. I have not tried these outside. I usually leave my outside cfl on 24/7 in cold weather, because they die out more quickly if you turn them off and on all the time in the cold.

LED's work as well in cold weather as in warm weather. Fluorescents get weak kneed.

LED bulbs work just fine outside, and are not impacted by cold like CFL bulbs are. I have several outside and they have suffered no ill effects.

It's "instant on", but, like all fluorescent lights, it will take a minute or two to obtain full brightness. The colder the temperature, the longer it will take. Note that the narrow base can be a great advantage in fixtures with limited space.

I've noticed the same thing Oleg mentions, the bulb really collects dust and lint on it. Having said that I did discover LEDs are sensitive to temperature. Most manufacturers' published ratings of LEDs are for an operating temperature of 25 °C. LEDs used outdoors, such as traffic signals or in-pavement signal lights, and that are utilized in climates where the temperature within the luminaire gets very hot, could result in low signal intensities or even failure (http://en.wikipedia.org/wiki/Light-emitting_diode).

Hi, what has the temperature been outside your home lately? I have my lights installed for over 6 years without a problem but two sets have been acting up lately by not coming on or not going off. We have had frigid temps in the NE for over a month. Might be related.

Yes i been useing cfls in one of mine for about a year, but in cold weather it takes a few minutes to warm up to full brightness, i could not stand using cfls in the house so i am using them in my heath/zenith.

I have been using the light since Mid-April. I have not had any issues with it. The temperature range has been normally 50 - 80 degrees. As far as it working in freezing temperatures, there have been several days of cold weather, but not any extended freezing cold temperatures. I live in Southern New England and I guess I will find out in a few short months.

On the back of the cover it says 200 degree Celsius (that is equivalent to 392 degree Fahrenheit or 473.15 Kelvin). But light color is very much equal to original bulb not very bright. I guess less bright may have more life.

It seems to be about that. I use mine for my porch light and it has been working in temps as low as 40 below. I have a 60w equivalent also and it seem about right too. This has the soft white color so it has the incandescent color.

Yes, mine is working outside, but note the colr of the one I revived is very night white. My other halogen bulbs a little yellow in color. Not a great match.

My experience is instant on. These bulbs come on instantly to full intensity even on the coldest nights, -20f.

Higher operating temperatures may shorten the life of an LED but I don't think it's something to be worried about. Colder temps should have no effect on it.

It lasted all last winter. A good rule rule might be to use the advertised bulb life and reduce by say 20% for the triggered on and offs.

put two replacement bulbs in a couple of weeks ago and too early for me to say if they will frost. I am not using currently except to do maintenance work and restoration. Sorry I can not give you the answer you are looking for - Ron
